Multi-band Wireless Channel Measurements in High-mobility Environment

Future mobile communication systems include millimeter wave (mmWave) frequency bands and high mobility scenarios. To learn how wave propagation and scattering effects change from classical sub 6 GHz to mmWave frequencies, measurements in both bands have to be conducted. We perform wireless channel measurements at 2.55 GHz and 25.5 GHz center frequency at velocites of 40 km/h and 100 km/h. To ensure a fair comparison between these two frequency bands, we perform repeatable measurements in a controlled environment. Our measurement methodology enables measurements at the same transmitter and receiver positions and velocities, but at different center frequencies.

未来移动通信系统涵盖了毫米波（mmWave）频段以及高移动性场景。为探究波传播与散射效应如何在经典低于6 GHz频率与毫米波频率之间发生变化，必须在这两个频段进行测量。我们在2.55 GHz和25.5 GHz的中心频率下，以40公里/小时和100公里/小时的速度进行无线信道测量。为确保这两个频段之间的比较公正，我们在可控环境中进行可重复的测量。我们的测量方法允许在同一发射器和接收器位置及速度下进行测量，但中心频率不同。
